Video Find: Hennessey Cadillac CTS-V Wagon Volume Goes To 11

The Cadillac CTS-V wagon may have lost out to the Porsche Panamera Turbo in our recent Three Loko comparo, but we still can't stop thinking about General Motor's super wagon that we used to terrorize the deserts just outside of Las Vegas. The folks over at Hennessey Performance decided to have some fun with the wagon, too, by showing off its latest video of a CTS-V wagon, this time equipped with the V650 Upgrade Package and Exhaust Dump option.

At the start of the video, the driver revs the engine a bit to demonstrate the "normal" exhaust note, which is definitely loud and respectable. But as soon as the driver flips a switch and dumps the exhaust, the wagon emits a loud, eye-opening growl. The video continues on to a burnout demonstration, shown at two different angles while providing another aural treat--a mechanical whine which could only be made possible from the supercharger. The wagon executes a 1st to 2nd gear burnout and disappears like a smoke and mirrors magic act.

But your eyes aren't deceiving you. This is raw performance made possible by Hennessey's V650 Package, which already improves on the stock supercharged V8 similar to the one in the Corvette ZR1. The V650 includes a supercharger pulley and snout upgrade, new headers, intercooler heat exchanger upgrade, high-flow catalytic converters, and Hennessey badging inside and out. Most importantly, the package bumps horsepower up to 658 vs. 556 in stock form, while torque jumps to 661 pound-feet, up from 551.
